Event Study Methodology

This study investigates the impact of COVID-19 pandemic on daily stock returns in Kuwait Stock Market (KSE) over the period from 28 March to 20 April 2020. By applying the event study methodology (ESM) approach, the results reveal that the pandemic has positively impacted stocks of banks, consumer goods and telecommunications sectors. However, oil & gas, real estate, financial, basic materials, industrials, consumer services, and insurance stocks have been negatively impacted by the pandemic. The COVID-19 pandemic's most negatively affected are services and financial stocks. The cumulative average abnormal returns (CAAR) of all sectors were affected negatively by the COVID-19 pandemic.

Event Study Methodology

This article investigates the market reaction to a sample of announcements of business service outsourcing arrangements made by UK quoted companies between 1991 and 1997. Event study methodology is applied to daily stock returns to measure the reaction, in the form of excess returns, immediately prior to and at the date of an outsourcing contract announcement. The conclusion is that initial announcements tend to enjoy positive and significant reaction and that the larger companies in the sample show a more positive reaction than smaller companies. Overall outsourcing announcements appear to be associated with excess returns but the absence of any recognized basis for disclosure prevents a complete analysis of such events.

Adjusted Residual

This paper examines Multinational Stock Price reactions to foreign currency translation, using three alternative residual methodologies. The results reveal that when a crude measure such as Mean Adjusted Return, which makes not explicit risk adjustments is used, the null hypothesis of zero abnormal return is rejected in three out of six events. However, market and risk adjusted residual returns reveal that the null hypothesis of zero abnormal return cannot be rejected.

The Impact

PurposeThis study investigates the effects of the COVID-19 outbreak on daily stock returns for the six major affected WHO Regions, namely: Africa, Americas, Eastern Mediterranean, Europe, South-East Asia and Western Pacific.Design/methodology/approachThis study uses an event study method and panel-data regression models to examine the effect of the daily increase in the number of COVID-19 confirmed cases on daily stock returns from 1 March to 1 August 2020 for the leading stock market in major affected countries in the WHO regions.FindingsThe results reveal an adverse impact of the daily increasing number of COVID-19 cases on stock returns and stock markets fell quickly in response to the pandemic. The findings also suggest that negative market reaction was strong during the early stage of the outbreak between the 26th and 35th days after the initial confirmed cases. We further find that stock markets in the Western Pacific region experienced more negative abnormal returns as compared to other regions. The results also confirm that feelings of fear among investors turned out to be a mediator and a transmission channel for the effect of COVID-19 outbreak on the stock markets.Research limitations/implicationsThis study contributes to financial literature in two ways. First, we contribute to existing literature that has examined the effect of various catastrophes and crises on the stock markets Second, we contribute to the recent emerging literature that examines the impact of COVID-19 on financial markets.Practical implicationsThe study may have implications for policymakers to deal with this outbreak without triggering uncertainty in stock markets and reassure investors' confidence. The study may also be of interest to investors, managers, financial analysts by revealing how the stock markets quickly respond to outbreaks.Originality/valueThis study is the first study to examine the impact of the COVID-19 outbreak on the leading stock markets of the WHO regions.
